You should power up HDD with external usb charger. The USB port in this device was designed to support only low power devices and protected via chip that burns out when you draw too much current.

Ow sorry then I misunderstood you.

The external HDD has his own power.

Did you connect HDD via USB only? If so probably usb overcurrent protection died. Few pages back you can find photo of the SMD chip on board that should be removed to make usb working again.

Yes I did, is that not correct?

starting to read trough these 86 pages of information.

But maybe somebody want to give me a hint where to find the answer.

I have a NVR, but the mouse stopt working after I added an external HD.

I tried to restart, several times, whit and without HD, with and without mouse.

Maybe there is a way to reset the system?

This is the way I connected the system:

4 camera's --> POE --> netwerkswitch --> NVR -- > monitor & mouse
